Cannot decide which hike should I go, which one has a better view?
Hopefully the weather will allow you to have a view! We hiked up Mt. Qixing. It was sunny when we started but unfortunately clouds rolled in and it started to rain and by the time we reached the top there were no views. We walked back through Xiaoyoukeng and as we got lower the clouds lifted. We enjoyed the volcanic area with the fumaroles. We did go to Qingtiangang as well (a lava terrace that is now a flat vast grassland with cattle). It was cold and raining again and windy. So we didn't go far there. I believe there is a circular trail but you can also walk from Lengshuikeng to Qingtiangang.
So as we did not have much of a view I can't really help but I would choose Mt. Qixing as I think that would be the better view.
